[0002] Rainwater and sewage separation is a drainage system that separates rainwater and sewage, and transports them through pipes for discharge or subsequent treatment. Rainwater can be discharged directly into the river through the rainwater pipe network, and sewage can be collected through the sewage pipe network and sent to the sewage treatment plant for treatment, thus avoiding sewage directly entering the river and causing pollution; at the same time, the collection, utilization and centralized management and discharge of rainwater can reduce the treatment pressure of sewage treatment plants.

[0003] In the prior art, for example, a kind of assembled rainwater and sewage diversion inspection well disclosed by Chinese patent announcement number CN214940843U includes a device body, a right inspection well cover is fixedly installed on the top of the device body, and a water inlet connection port, a sewage connection port and a rainwater connection port are evenly arranged on the bottom outer wall of the device body, and a water inlet pipe is sleeved on the inner wall of the water inlet connection port, a sewage pipe is sleeved on the inner wall of the sewage connection port, and a rainwater ditch is sleeved on the inner wall of the rainwater connection port. Through the designed fixed baffle, the first movable baffle and the second movable baffle, when the device is in use, rainwater with a small water flow rate is discharged into the rainwater ditch through the hole opened on the first movable baffle, and sewage with a large water flow rate is moved by impacting the first movable baffle, and then the first movable baffle is used to push the second movable baffle, so that the sewage pipe port is exposed, and the sewage is discharged through the sewage pipe.

[0004] However, the rainwater ditch and the sewage pipe in the inspection well are both connected to the device body, and no complete diversion is achieved. In actual use, due to the poor sealing between the movable baffle and the inspection well, the rainwater ditch and the sewage pipe are connected. Utility Model Content

[0005] The utility model provides a rainwater and sewage diversion inspection well, aiming to solve the problem that the inspection well mentioned in the background technology cannot realize the complete diversion of rainwater and sewage.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] Example

[0031] Refer to the attached drawings of the specification, such as Figure 1-Figure 5 As shown, a rainwater and sewage diversion inspection well includes a drainage node 1, a plurality of sewage pipes 2 and a rainwater ditch 3.

[0032] Among them, Figure 1 As shown, a side wall 11 is arranged around the drainage node 1, and a bottom plate 15 is arranged at the bottom of the drainage node 1. The bottom of the side wall 11 is fixedly connected to the bottom plate 15, and the drainage node 1 forms a structure with an open top and a hollow interior. One or more sewage pipe openings 13 are arranged on the side walls 11 around the drainage node 1, and multiple sewage pipes 2 are connected to the sewage pipe openings 13. A rainwater ditch 14 is arranged on the two opposite side walls 11, and the rainwater ditch 3 is erected on the rainwater ditch 14 on the two side walls 11. When the rainwater ditch 3 is erected, its two side surfaces are stuck in the rainwater ditch 14. Under this structure, rainwater passes through the rainwater ditch 14 for subsequent treatment, and sewage passes through the sewage pipe 2 for subsequent treatment. The material of the rainwater ditch 3 can be resin concrete or plastic, so that the weight of the rainwater ditch 3 is lighter and the space occupied by the rainwater ditch 3 is smaller. The cross-sectional shape of the sewage pipe 2 is circular.

[0033] Further, such as Figure 2 As shown, the sewage pipe opening 13 and the rainwater ditch 14 on the same side wall 11 are staggered. Figure 2 In the embodiment, the rainwater groove 14 is located at the upper left corner of the side wall 11, and the sewage pipe opening 13 is located at the lower right corner of the side wall 11. Figure 3 As shown, for the side wall 11 only provided with the sewage pipe opening 13 , the sewage pipe opening 13 on the side wall 11 is arranged at the bottom center of the side wall 11 .

[0034] like Figure 1 As shown, a first cover plate 12 is provided on the top of the drainage node 1, and the bottom of one side of the first cover plate 12 contacts the top of the side wall 11. The first cover plate 12 is movably connected to the side wall 11. Specifically, the first cover plate 12 may be a concrete plate. The first cover plate 12 contacts the side wall 11 but is not fixed. By taking the side of the first cover plate 2 in contact with the side wall 11 as the rotation axis, the side of the first cover plate 2 away from the side wall 11 is lifted, so that the first cover plate 2 rotates on one side of the rotation axis, thereby realizing the lifting and lowering of the first cover plate 2.

[0035] like Figure 1As shown, a second cover plate 31 is provided on the top of the rain gutter 3, and a water inlet 32 ​​is provided on the second cover plate 31. When the first cover plate 12 and the second cover plate 31 are both in the covering state, the first cover plate 12 and the second cover plate 31 are completely covered and shielded on the top of the drainage node 1. At this time, rainwater can only enter the rain gutter 3 through the water inlet 32 ​​on the second cover plate 31, and cannot enter the drainage node 1 through the space between the first cover plate 12 and the second cover plate 31, and the position of the first cover plate 12. The second cover plate 31 is detachably connected to the rain gutter 3. Specifically, both sides of the second cover plate 31 are in contact with the rain gutter 3 but are not fixed. The second cover plate 31 can be directly lifted or placed on the rain gutter 3. In addition, as Figure 1 As shown, the second cover plate 31 may include a plurality of second cover plate units 311; adjacent second cover plate units 311 are seamlessly connected to prevent other debris exceeding the size of the water inlet 32 ​​from falling into the rain gutter 3 from the gaps between the second cover plate units 311. Further, the water inlet 32 ​​on the second cover plate 31 is in an elongated strip shape to increase the opening size so that rainwater can fall into the rain gutter 3 more quickly. The inner wall cross-section of the rain gutter 3 is in a "U" shape.

[0036] In addition, the drainage node 1, sewage pipe 2 and rainwater ditch 3 can all be prefabricated as finished products, and the sizes of the sewage pipe outlet 13 and the rainwater ditch 14 are respectively adapted to the sizes of the sewage pipe 2 and the rainwater ditch 3, which facilitates the installation and use of the drainage node 1 and the sewage pipe 2 and the rainwater ditch 3.

[0037] Based on the above structure, this application has the following advantages:

[0038] 1. The sewage pipe 2 and the rainwater ditch 3 are respectively arranged at different positions of the drainage node 1, and the sewage pipe 2 and the rainwater ditch 3 are not connected, so that rainwater and sewage are completely separated, and the treatment of rainwater and sewage is independent of each other; the drainage node 1, the rainwater ditch 3 and the sewage pipe 2 can be prefabricated as finished products, and the sizes of the rainwater ditch 14 and the sewage pipe outlet 13 are respectively adapted to the sizes of the rainwater ditch 3 and the sewage pipe 2, which is convenient for the installation and use of the drainage node 1, the rainwater ditch 3 and the sewage pipe 2.

[0039] 2. The sewage pipe 2 and the rainwater ditch 3 are both arranged at the drainage node, which saves the installation space of the sewage pipe 2 and the rainwater ditch 3, so that the rainwater and sewage diversion inspection well can be used in narrow alleys in a narrow area, thereby increasing the use scope of the rainwater and sewage diversion inspection well.

[0040] 3. Compared with the traditional concrete structure, the rain gutter 3 is made of resin concrete or plastic material, so that the rain gutter 3 is lighter and occupies less space.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
